Question

As the earth orbits the sun, the tilt of the earth exposes equatorial regions to direct sunlight more than the poles. This is the primary cause of temperature differences between equatorial regions and the poles. With this in mind, what other phenomena would logically be caused primarily by the earth's axial tilt?

a.the movement of tectonic plates
b.climate change
c.the earth's gravitational field
d.seasonal changes on earth

Answer 1

The primary phenomenon logically caused by the Earth's axial tilt is seasonal changes on Earth. the correct option is (d).

Step-by-step explanation:

The Earth's axial tilt, which is approximately 23.5 degrees, is the primary cause of seasonal changes on Earth. As the Earth orbits the sun, different parts of the Earth receive varying amounts of sunlight throughout the year. This variation in sunlight exposure leads to the changing seasons.

Options a (the movement of tectonic plates), b (climate change), and c (the Earth's gravitational field) are not primarily caused by the Earth's axial tilt:

a. The movement of tectonic plates is driven by processes in the Earth's interior, primarily related to the heat generated by radioactive decay.

b. Climate change involves complex factors, including human activities such as the burning of fossil fuels, deforestation, and industrial processes, along with natural processes. It is not primarily caused by the Earth's axial tilt.

c. The Earth's gravitational field is influenced by the distribution of mass on and within the Earth, including the presence of mountains, oceans, and variations in density. While the Earth's axial tilt may have a minor effect, it is not the primary cause of variations in the gravitational field.
